SPECIFICATION forming part of LetterslPatent No. 278,668, dated May 29, 1883.

Application filed May 7, 1893. (No modeLl Patented-in Mexico January 25, 1883. f i i To all whogn it may concern: I

Be it known that LDEMETRIO PRIETO, a.

citizenofSpain,residing at Mexico, in the ltepubliciof Mexico, have invented certain new "and useful Improvements ina Machine for Disintegrating Fibrous Plants; and-I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which} The chains I I are composed of open links; but the links it of lower chain, K, are closed,

it appertains to make and'use the same.

The object of my invention is to provide a new and improved machine for extracting the fiber from those plants the fiber of which is or may be usedtfor commercial purposes, and to especially adaptit for use in cleaning those plants indigenous to tropical climates, and particularly of the bromelia and kindred classes.

It consists,in combinationwith a suitable frame, of a set of crushing groove-rollers, carr in -chains friction-rollers and sore. )in

knives, by which the plants are firstbroken or crushed, then carried to one set of knives, by

which one part of the plant is scraped, and

then to another set of knives, by which the remainin g part'is scraped and all matter removed except the fiber. It is illustrated in the accompanying drawings, in which- Figure 1 isa plan. view; Fig. 2, an end a 1 .view; Fig. 3,afront view; Fig. 4,an enlarged horizontal sectional view of a portion of the machine to the right of the line 2 2, Fig. 3; and Fig. 5, a side sectional view on line pr or of Fig. 4. y

The same letters designate corresponding parts in the several views.

A is the frame of the machine; B B, removablecovers of the bladedscraping-wheels,

which covers are used to prevent the acid. juices of the plants, as they are scraped, from being thrown on the operatives.

0.0 are adjustable crushing groove-rollers mounted on one side of the machine andrevolvingtoward each other to crush the plants and "carry them forward to the cleaning mechanism. They are adjusted vertically as to pressure by thumb-screw c. On the shafts of thesame rollers are secured disks c having projecting teeth 0 As the plants are fed lengthwise to the rollers 0 they are caught by the teeth 0 which aid to guide and feed them through the crushing-rolls.

and are provided with recesses in their under surfacefor the reception ofthe pins on' the wheels. The upper surface of said links is y provided with a central rib, W, on both sides of which are secured rubber strips 75*. This rubber stripping acts as an elastic cushion for thechains I I and prevents the plants from being torn as the same are carried between the upper and lower setof chains.

0 and 0' 0 0 are small anti-friction rollers, between which the chains I I and K are carried. The upper set of rollers, 0, have their bearings in a frame, N, which is adjustable vertically by thumb'screw P, by which the pressure of thecarrying-chains upon theplants may be varied and controlled. I

R is a circular disk having saw-teeth,and mounted on'a shaft between the two wheels D D to aid in carrying the plants from wheel D to wheel D. I

The actuating mechanism consists of pulleys l 2, mounted on the shafts 3 4: of the scraping- Wheels, and from which bands may be led to 8 5 any suitabledriviug mechanism. Motion imparted to shaft 3 is communicated through bevel-gearin g s to the crushing-rolls, and also through worm T and cogs V to .disklt, and the upper and lower chains, I I and K.

In the operation of dressing the plants they are presented, as already stated, lengthwise to the machineand carried between the crushof the plant is stripped,whereupon the operroofation is completed. I Having thus described my improvement,

2 castes k g what 1 claim, and desire to secure by Lettersjustable crushing-rolls, the carrying yielding adjustable chains, the duplicate wheels, and

their blades, whereby the plant is first partly crushed, then carried between the elastic supports, one end of the plant cleaned, and then carried forward and the rem aining end clea ned,

' substantially as described.

2. In a machine for disintegrating fibrous plants, the combination of the adjustable groove crushing-rollers and the revolving disks, and projecting teeth forfeeding and crushing the plants, substantially as described.

3. In a machine for disintegrating fibrous plants, the combination, with'suitable mechanism, ot' the sets of carrying-chains, one set provided with an elasticsurface, substantially as and for the purpose described.

4. In a machine for disintegrating fibrous plants, the combination of the chains Iand K and vertically-adjustable anti-friction rollers, substantially as and for the purpose described.

5. In a machine'for disintegrating fibrous plants, the wheels D and D, provided with the adjustable blades E, and suitable mechanism for carrying the'plants between said wheels, whereby one end of the plant is cleaned, and then the opposite end, substantially as described. v a g 6. In a machine for disintegrating fibrous plants,the combination of therevolvin'gtoothed disk R and the carrying mechanism, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

DEMET'RIO PRIETO.
